You can do that? logarithm of a rotation @drpeyam

Uploaded April 2023 | Updated September 2026, 1 week ago

logarithm of a rotation. We calculate ln of a rotation matrix and see a really cool result from linear algebra. We then generalize this to 3 dimensions with Lie groups and so 3 and using metrics of matrices and Rodriguez formula. This is a must see for any calculus and linear algebra student!

You can do that? logarithm of a rotation

How many tangents to this ellipse? (no calculus)

not your AVERAGE Putnam limit (2021 Putnam A2)

$This integral will have you on the floor 🤣🤣 Integral of 1 over integer part of 1/x from 0 to 1. I calculate a nice integral with a floor function by using Riemann sums and using telescoping series, it’s a must see for calculus lovers. The answer involves the Euler Mascheroni constant Integral fractional part of 1/x https://youtu.be/uaVwP2K6MIM YT channel: https://youtube.com/drpeyam TikTok channel: https://www.tiktok.com/@drpeyam Instagram: https://www.instagram.com/peyamstagram/ Teespring merch: https://teespring.com/stores/dr-peyam$
